New Feature for Old MEDLINE

NLM® is embarking on a project to map the OLDMEDLINE subject headings, found in the PubMed® Other Term [OT] field, to current MeSH®. The original subject headings will be retained in the OT field. NLM expects to have a large percentage of this project completed for the new 2006 PubMed system in mid-December 2005.

See the NLM Technical Bulletin for more details.
